I've been seeing EXTREMELY nice stepping xp1700+s on the buy sell trade forum lately. Just picked up an unknown jiuhb dut3c which probably won't do great but it's not for my main 2 systems. A few very well known dlt3c's have shown up lately hot off the excaliber press; the present owner's lack of luck with 'em may be your gain.
I bought my first dlt3c xp1700 on another forum and it's been really stable at 2352 - think the guy who bought it originally was hoping for 2500 stable, if you go to the overclockers.com site they always have high numbers but I think those guys barely boot into windows sometimes and have huge w/cool peltiers usually. I like my little 62% o/clock so well I bought the exact same stepping off ANOTHER forum by "searching" 1700 every night on a few forums buy sell trade. I would rather do that than buy and return at fry's or cry when a tbred a from newegg shows up - I've really become a 1700 junkie. I suggest that.
